Macrosomia is a condition in which a baby is abnormally large before birth. The average birth weight for babies is about 7 pounds. Babies with macrosomia have a birth weight of at least 8 pounds, 13 ounces or more.
Macrosomia occurs in more than 10% of all pregnancies in the United States. It may lead to pregnancy complications such as a greater risk of cesarean delivery, damage to the birth canal, and injury to the baby during a vaginal delivery.
Babies born with macrosomia are more likely to have low blood sugar, respiratory distress, and jaundice.
